    Dear Paul,

    Congratulations !

    With your data, I am also computing a 0.0 NM intercept for a true azimut of 27.1 °.

    Best Regards


    Note : 1 - Most generally, ALL the On Line CelNav Software available on the Internet will perform very accurate Apparent positions for the Stars (certainly well under 0'1), which is again verified with the "Navigation" Software you are using. Accurate Star apparent ccordinates are fairly straightforward and easy to compute with an accuracy of 1" for example.

    2 - Have you tried the On Line Celnav Software such as US Naval Observatory ?

    It is here : http://www.usno.navy.mil/USNO/astronomical-applications/data-services/cel-nav-data .

    Obviously, all Governement Agencies (USNO, and others) compute very accurate CelNav Bodies apparent positions for any time / date in the full range of their validity dates.
